Jitsi meet jwt token authentication enable

I installed jitsi-meet on ubuntu 18.04(bionic)
I run these commands to enable jwt token authentication

wget https://packages.prosody.im/debian/pool/main/p/prosody-trunk/prosody-trunk_1nightly747-1~xenial_amd64.deb
dpkg -i prosody-trunk_1nightly747-1~xenial_amd64.deb

then

sudo apt-get install libssl1.0-dev

and then

sudo apt-get install luarocks

sudo luarocks install luacrypto

and then finally
sudo apt-get install jitsi-meet-tokens

vi /etc/prosody/prosody.cfg.lua

Include “conf.d/*.cfg.lua”

c2s_require_encryption=false

prosodyctl restart

also i change this line

but I got these error

These are just file permission errors, if you haven’t installed jitsi-meet with domain name localhost you can just ignore those.
